Nucleases and ligases
Nucleases are enzymes that cut DNA strands by catalyzing the hydrolysis of the phosphodiester bonds.
Nuclease. A class of enzymes that degrades DNA and/or RNA molecules by cleaving the phosphodiester bonds that link adjacent nucleotides. In deoxyribonuclease (DNase), the substrate is DNA.
Exonuclease
An enzyme that digests a molecule of nucleic acid by removing successive nucleotides from the 5' or 3' end. Exonucleases may be specific for single or double stranded DNA or RNA, and may be specific for either 3' or 5' ends.
Exonuclease: An enzyme that cleaves nucleotides sequentially from free ends of a linear nucleic acid substrate.
Expressed gene: See gene expression.

Exonuclease: A nuclease that degrades a double-stranded DNA molecule by removing nucleotides from its two ends. Exonucleases can be specific for digestion from the 3' or 5' ends of the nucleic acid.
Exonuclease An enzyme that digests nucleic acids from the ends of the molecule, rather than at an internal site; exonucleases can be specific for digestion from the 3' or 5' ends of the nucleic acid.
Nuclease
An enzyme which cleaves phosphodiester bonds that link adjacent nucleotides in DNA and/or RNA.
Nuclease: An enzyme which degrades nucleic acids. A nuclease can be DNA-specific (a DNase), RNA-specific (RNase) or non-specific.

A restriction map shows the positions at which specific short base sequences (i.e. restriction enzyme recognition sites) occur in a DNA molecule. Restriction maps are made using a specific type of endonuclease (an enzyme which cuts DNA within ...
restriction endonuclease. An enzyme that cleaves a DNA molecule at a particular base sequence.
restriction endonuclease - aka restriction enzyme - bacterial enzyme that cuts double-stranded DNA at a specific sequence.
See DNA, nuclease. Diabetes. A disease associated with the absence or reduced levels of insulin, a hormone essential for the transport of glucose to cells. Dideoxynucleotide (didN).
The name is derived from the fact that these sequences are cleaved by the restriction endonuclease Alu. Amino acid sequence -- the linear order of the amino acids in a protein or peptide.

Lysosomes are full of a variety of digestive enzymes (amylases, peptidases, nucleases, lipases) which break down "old" biomolecules and also old organelles. Their function is essential to the health of the cell.
One of these genes might be what's called a nuclease. Nucleases are things that degrade nucleotides. If Deinococcus was somehow able to better control its nucleases or even delete them altogether it might become more radiation resistant.
Landmarks include restriction endonuclease recognition sites, DNA sequence and chromosomal bands. Distance is measured in base pairs.
Restriction enzyme, endonuclease: A protein that recognizes specific, short sequences of DNA and cuts at those sites. See also Restriction enzyme cutting site.

Alus are approximately 300 base pairs long, often contain a site for the restriction endonuclease Alu I and have been derived from a small number of active members via transcription and retroposition (which still continues).
